"You may not rest, there are monsters nearby."
-Sun Tzu, The Art of War.
Alright, listen up, smoothbrain. The joke is that Sun Tzu, who wrote "The Art of War", which is all about, well, war, is saying that you can't rest because there are monsters nearby. It's funny because it's unexpected. Like finding out your mom knows how to play Fortnite. By the way, your brain is smoother than a baby's bottom.
